Nicer debug -> temperature graph

Lowered the scale -10 ºC so it accomodates less than zero temperatures, present sometimes when cold starting the system.

Added 1 char for temperature label length.

Adjusted the max2837 sensor value -> ºC temp result, by normalizing the conversion to correctly display the standard 25ºC, mentioned in Datasheet.
